Gas therapy is actually drawing attention in nanomedicine as a safe and therapeutically efficient technique. Indeed, the design of stimuli-responsive nanocarriers with controlled release is encouraging to heal without any risk of gas poisoning. Here, we review recent developments of gas nanogenerators and gas-releasing molecules for controlled and targeted gas therapy in cancer nanomedicine. We present gases used in anticancer therapy, such as hydrogen, carbon dioxide, sulfur dioxide, hydrogen sulfide, oxygen, carbon monoxide, and heavy gases. The construction of gas nanogenerators and gas-releasing molecules with unique biological and physicochemical properties has allowed targeted and controlled release of gas molecules. We describe the stimulation method for each gas, along with gas nanogenerators and gas-releasing molecules.

实际上，气体疗法作为一种安全且治疗有效的技术正在引起纳米医学的关注。实际上，具有可控释放的刺激响应性纳米载体的设计令人鼓舞地治愈，而没有任何气体中毒的风险。在这里，我们回顾了用于癌症纳米医学中受控和靶向气体治疗的气体纳米发生器和气体释放分子的最新发展。我们介绍了用于抗癌治疗的气体，例如氢气，二氧化碳，二氧化硫，硫化氢，氧气，一氧化碳和重气体。具有独特的生物学和物理化学性质的气体纳米发生器和气体释放分子的构造允许气体分子的靶向和控制释放。我们描述了每种气体以及气体纳米发生器和气体释放分子的激发方法。
